https://www.superbrightleds.com has been recommended to me by a reliable source. I haven't purchased anything from them yet so I don't have direct experience.
TreeSeeker - 1141 bulbs are quickly becoming obsolete and replaced by the much more commonly used 1156 bulb. (1141 is rated at 264 lumens and 1156 at 402 lumens so 1156 is slightly brighter than 1141.) My research has focused on more common bulbs so I haven't researched E26 bulbs.
If your interior lighting levels suit you, go with the equivalent LED replacements with the same lumen ratings as the old incandescent bulbs. You're probably going to have to -- and should -- switch to the 1156 equivalent LED replacements. The increase in light emitted should be barely noticeable, if at all.
Normally, there'd be some concern due to increased current draw (1141 @ 1.44 amps versus 1156 @ 2.1 amps equals a 50 percent increase in current load). Switching to LEDs means a drastic decrease in current load so that concern is eliminated.
For your task light, look for a fixture made with LEDs rather than an incandescent fixture and bulb swap. LED replacement bulbs need to mimic the spherical emission pattern of incandescent bulbs to qualify as equivalent. Based on my experience with incandescent task lights, you'll probably want an LED fixture with roughly 400-500 lumens.
One of the advantages of LEDs is they can be focused in conical or semi-spherical emission pattern. This eliminates the need for reflectors to redirect incandescent spherical emission. (This is the reason for part of the Thin-Lite LED112P's higher lumen rating versus an incandescent fixture/LED bulb swap combination.)
BYW - as you explore LED possibilities, you'll probably run into mention of SMDs, which means Surface Mount Devices. This is newer KED 'packaging' that reduces manufacturing costs and dimensional limitations. (LED SMDs are about the size of a small finishing nail head, compared to the 3/16-1/4" diameter of older LED 'packaging.')
